WOOD-SHAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 268,405, dated December5, 1882.

Application filed J line 15, 1882.

To all whom it may concern:

Be it known that I, JOHN W. HUDSON, a citizen of the United States ofAmerica, residing at WVellington, in the county of Iroquois and State ofIllinois, have invented an Improvement in Shaping-Machines, of which thefollowing is a specification.

My invention relates to a machine for cutting and finishing hames orother irregular shapes.

The object of my invention is to provide a machine for working irregularforms, particularly adapted for making hames for harness; and myinvention consists, first, in a peculiar arrangement of movablerevolving spindles carrying the cutting or finishing heads, and moved toconform to the shape of the work by camways in a reciprocating table onwhich the work is placed second, in a double set of movable spindles,one set of which is provided with cutting and the other with smoothingo1- finishing heads, and so arranged that while one set is in positionfor work the other is thrown out; and, third, in certain combinationsand arrangement of parts, as hereinafter fully described with referenceto the accompanying drawings, in which- 7 a Figure l is a plan view ofmy improved machine. Fig. 2 is a side elevation, Fig. 3 a longitudinalsectional elevation, and Fig. 4: a transverse sectional elevation, ofthe same. Figs. 5 to 10, inclusive, are views of some of the variousparts shown in detail, and more directly referred to hereinafter.

Like parts are represented by similar letters of reference throughoutthe several views.

In the said drawings, A A represent the main frame of the machine, whichI prefer to make of iron, consisting of the side pieces A A, each castin a single piece, and firmly connected together and braced above andbelow to secure the proper strength and stability.

13 is the reciprocating or sliding table, which consists substantiallyof an upper and lower table, B and B which are made exactly alike, andfirmly connected together and securely braced by connecting-pieces b andbraces 11. The table Bis provided on each side at the top and bottomwith V-shaped ways 6, which slide in correspondinglygrooved pieces 0,secured to the main frame A A at the bottom,

(No model.)

and similarly-formed projections c at the top. Running lengthwise of thetable B in the top and bottom plates,B and B are camways 0 G, bounded oneach side by steel plates P, through which project the spindles S S andS S, which are journaled above and below in sliding bearings d d, whichmove freely in slides a at, extending across the machine above and belowthe table B, those, a, at the bottom having their ends rigidly attachedto the side frame-pieces A A, while those, a, at the top are arranged tobe raised or lowered vertically, as and for the purpose hereinafter morefully set forth. The spindles S and S are turned down at the upper end,where they enter the bearings, with a shoulder at-the bottom of thebearings, and are provided at the top with nuts or n, which prevent anyend-play of the spindles through the bearings d, but at the lower endare left full size, and are free to move Vertically through the bearingsd.

To the spindles S, directly under the bearings d, are secured thecutter-heads h, which may be of any desired size, provided withproperly-shaped cutters to correspond to the work to be done, and havingtheir lower ends resting directly on the steel plates 1? at the sides ofthe camways G. In asimilar manner to the spindles S are secured thefinishing or smoothing heads h, which are made similar in shape to thecutting-heads h, but instead of cutters are provided with pieces, [L2,of steel, cut in the manner of a rasp. (See Fig. 10.) The upper slides,a a, on which the bearings d 01 move, are arranged in pairs securedtogether at each end, and arranged to move vertically in verticalrecesses a a in side pieces D, secured on each side of the main frame AA. Each set of slides are connected together at the ends by cross-barse, to the center of each of which is attached a link, 6 connected at itsother end to an oscillating lever, L, secured on a square rod or shaft,f, journaled at each end in bearings f on the side pieces D, andprovided at one end with a hand-lever, E,which extends at its outer endthrough the adjustable pressure-yoke K,secured tothe side of the frame AA. (See Figs. 2 and 7.) By this arrangement, upon raising the hand-leverE the out ting-heads h are brought in position for work,

while the finishing-heads h are raised up out 2 seams of the way, asshown in Fig. 3, and vice versa.

The adjustable yoke K, referred to above, is shown in detail in Fig. 8,and consists of a pipe or sleeve, g, secured to the main' frame A A,bored out for a portion of its length from each end, with the ends 4; tof a loop, I, fitting therein and resting against springs n n. Securedto the inner side of the loop Z is a bar, Z, hav' ing at each end aseries of notches, 0 0, with one of which a projection, 0, on the leverE is made to engage by means of a spring, 8, se cured' at one end tosaid lever and bearing against the opposite side of the loop Z.

R R are what I term the pressure-rollers, oneot' which is placedopposite each cutting and finishing head, and consists of a roller, r,provided with a spindle, r, journaled in a sliding box, 01 slidingbetween the bars a a, and connected to the bearing 61 of the spindle Sby a spring, 8, secured to the hearing by a setscrew, s, passing througha slotted hole, 8 which renders it adjustable. (See Fig. 9 for detail.)The spindle a" of the roller is turned down for a portion of its lengthand a coiled spring,t,placed thereon,thusallowingthe roller to yieldeither vertically or laterally. The hame or other article to be shapedis placed on the top of the table at F between the camways O, which areshaped at this point to correspond with the shape it is desired to cut.The cutting-spindles S S are revolved by means of belts G, running froma suitable source of power to pulleys 12 secured thereon, which are inturn connected to pulley p on the finishing-spindles S by belts G. Thepulleys p are not secured to the spindles S, but run loose thereon,being supported in their. places by a stand, H, which rests on thebearing 01 and encircles the spindle above and below the lower plate, B,ofthetable,with the connecting-shank j extending through the camway 0.(See Fig. 5.) Secured to the spindles S are clutch-collars u a, which,when the finishing-heads h are lowered into position for work, engagewith similar clutches on the top of the pulleys p and thus revolve thespindles S S. When the heads h are raised out of position the clutchesUbecome disengaged from the pulleys 19 which then run loosely on thespindles S while said spindles remain at rest.

In making hames with this machine the hame is first steamed and bent inthe rough to something near the required shape. The sliding table B ispulled back to its full extent, and the hame placed thereon at F, whichis provided with small points or stickers to hold it in place. Thecutting-spindles are lowered to their position and started to revolving.The table is then passed through. The spindles S S, moved by the camways0 0, move back and forth on the slides a. a to correspond to the shapeof the hame, the pressure-rollers R serving to hold it in place. Therebeing two outtin g-heads-one on each side-the hame is cut out on bothsides at once. After the hame has passed the cutting-heads thehand-lever E is pushed down, which raises the cutting and at the sametime lowers the finishing heads into position, as before described. Thetable is now drawn back and the hamethoroughly smoothed by the revolvingrasps. It is sometimes desirable to have the hame a little thicker inthe middle than at the ends. This is accomplished by having the steelplates P, on which the heads h or h rest when at work, slightly tapered,which gives the spindles a slight ver tical movement, which is permittedby reason of the adjustable pressure-yoke K. The steel plates P aresecured to the tables B B by screws 0 a which extend through slottedholes 6 c in the table, (see Fig. 9,) and are thus rendered adjustablein case of wear.

The camways U at the rear end of the table extend clear out, and aplate, P, being secured on the said ends of the table at the top andbottom, as shown -in Fig. 6. By removing these plates the table B may bewithdrawn from the frame N N and reversed, bringing the part B to thetop. This will reverse the camways, and furnish the means of makingright and left hames with the same machine.

If desired, the table B maybe fed automatically by the addition of arack and pinion, or

other well-known device for this purpose. The hand-lever E may be alsoarranged to auto matieally change the position of the cuttingandfinishing heads; or it may be done by hand.

It will be evident from the above description that by changing the shapeof the camyvays in the table and the shape of the cutters irregularforms of an infinite variety may be cut with this machine of varyingsizes, shapes, and thicknesses.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, i
